CAR BOLSTER AND SIDE BEARING,

Application led December 14, 1921. Serial No. 522,284.

To all w Lom t may concern Be it known that I, ALLEN E. Os'rRANDnR, residing at Ridgewood, Bergen county, New Jersey, and being a citizen of the United 5 States, have invented certain new and useful Improvements in a Car Bolster and Side Bearing, of which the Jollowin, is a full, clear, and exact description, such as will enable others skilled in the art to which it l appertains to make and to use the same, reterence being had to the accompanying drawings, which 'illustrate the preferred form of the invention; though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is' obvious that various modifications thereof within the scopel of the claims will occur to persons skilled in the art.

In said drawings:

Fig. 1 is a partial vertical sectional view of a tank car showing my invention applied thereto;

Fig. 2 is a vertical sectional view ot a part of the bolster shown in Fig. 1 taken on the line 2-2 o'fFig. 3;

Fig. 3 is a horizontal sectional View taken on the line 3-3 of Fig. 2, parts being broken away to show other parts more clearly;

Fig. 4 is a vertical sectional. view taken on the line 4-4 of Fig. 2. and

`Fig. 5 is a plan view of a part of the bottom cover plate ofthe bolster.

It is the obj ect ot my invention to provide an improved body bolster construction having diaphragms adapted to provide increased strength for the support of the load carried by the side bearings, a bottom cover plate of channel shape for part of its length so as to vreentorce the bolsterl diaphragms and side bearings fitting into the channelshaped portion of the bottoinvcover plate and having anchor means for use in securing the car body to the nnderframe.

I have shown my improved body bolster as applied to a tank car but it is to be Linderstood that my invention is not limited to the type of car shown.

As illustrated, a tank 1 is carried upon saddle blocks 2, 3 supported upon an underframe comprising center sills 4, spaced by a lilled piece 5 and joined by a cover plate 6, and holsters 7. The bolsters 7, only one of which is shown in the drawings, comprise pairs of diaphragms 8 having tapering webs 9 and outwardly projecting flanges 10. The

upper and lower flanges 10l of the da phragms 8 are joined by the top and botton bolster cover plates 11 and 12, respectively, which extend across the center sills 4 and for a part of the length of the diaphragms 8 on each side of the sills 4 and are riveted to the flanges 10. Secured to the upper flanges 10 by the rivets that secure the cover plate 11 thereto is a support` ing casting 13 that carries the block 3 and is provided with projecting flanges 14 that engage the block 2 and secure it in position on the cover plate 11. y

The webs 9 of the diaphragms are reenforced by means of tapering inclined corrugations 15 that extend part way down from the top flanges and merge into the webs where the webs are secured to a channelshaped portion of the bottom cover plate that projects into the space between the webs 9 of the diaphragms, the flange portions 16 of this channel-shaped portion being riveted to the webs 9 of the diaphragme and serving to reenforce the same while the web portion 17 of this channel-shaped portion serves as a spacing element and stiftener for the webs 9. Mounted in the channel-shaped portion of the cover plate 12 and secured in position by the rivets 18 that ser-ure the flange por tions 16 to webs9 is a side bearing 19 having a base portion 2O adajiited to receive a wear plate 21 and extending' beneath the bottom flanges 10 of the diaphragms to which it is secured by the bolts 22 that secure the'wear plate 21 to the base portion 20. The base portion 20 is extended to pro vide an anchor portion 23 in which is fastened an end of a strap 24 that serves to hold the body .l in position on the underframe.v Integral with the base portion 2O are projections 25 that are spaced so as to fit between the Harige portions 1G to which I they are secured by the rivets 18 and are extended to form a tapered continuous reenforcing flange for the anchor portion 23. Joining the projections 25 and integral with the base portion 2O and projections 25 is a reenforcing rib 26 having an inclined top portion that joins the upper portions of the projections' 25 and is engaged with the web portions 17 when the side bearing 19 is secured in position.

From the Jforegoing description it will be seen that I have provided a construction in which the loads carried by the side bearings are borne by diaphragm webs reenf'orced in the line of the greatest stress and trans'- Initted to the side bearings, in part, directly from the diaphragmsandfin part, through the connection of `'side bearing,:bolster-'bottom cover plate and diaphragm )vebs by means of rivets in double shear; It Will also be seen that I have provided a side ybearing that comprises an anchormeans for the car body and Which serves to reenforce the bol- Ster. N.
